Argos Customer Assistant interview questions

Application online stating most recent work experience and any additional things that would help your application. Invited to interview by email the next week. Didn't realise it was a group interview however was relaxed and informal. Split into pairs and asked to find out about your partner and relay back to group. Then the group was split into 2 and each had to design their perfect employee- bit of fun to test what you think makes a good customer assistant. Finally given brochures about insurance policies for products and also the argos card, to which in our pairs we had to do role play a customer and staff conversation, offering those things with a product description the interviewers give you. Overall fine but do not feel this is the best way to test someone as only 1 from each pair was allowed to showcase their customer service skills, while the other had to be a customer.
